YES accepts the current letter, Back deletes the last letter. Jump goes forward or back 5 in the scrolling text. - button slows down the scroller + speeds up the scroller. Swap reverses the scroll either forward of backwards. And the PC symbol Exits the App.

If someone wants this I will add the extra bit to Send the text the the top most window, or the window you can specify in the settings file. At the moment the text goes nowhere.
